Britney had a fun weekend in Vegas, taking her new boy toy Isaac to the Prince concert at the Rio Saturday night and then partying at the Palms last night with her pal, and Palms owner, George Maloof. It seemed Isaac was making an effort not to be photographed with Brit, as our cameras couldn't seem to get them in the same frame ... and there were 8 bodyguards making sure we couldn't get the shot!

Britney's looking good and I love her shoes! I guess she didn't anticipate the cool desert weather and had to cover up with Maloof's coat ... but other than that, HOT!
